5.3 first start wont start

I had 4 of 8 injectors clogged and replaced, found this out by pulling the Fuel Rail up and having a catch can and watching the injectors fire as we tried to start. The noid lights lit up like they were working b/c they were getting the right signals to fire.

Also if that doesnt work, make sure the VATS is turned off in the PCM.

Shon,
So once they are clogged, they can't be cleaned? I've got a couple of sets that have been sitting for a few years. More than likely they will be clogged too?
